The reality tv star hit back at "petty haters" on Instagram who pointed out her latest post-gym picture had clearly been digitally altered. And the Kocktails With Khloe host immediately confessed, showing the unretouched photo - but didn't explain why she changed it in the first place.

The only clear difference between the two is a slightly smoother thigh.

"If only hatin burned calories how dope yall would be. Too bad it doesn't. Here's the OG shot. The petty movement ain't cute. Oh and I almost forgot.... Namaste," she wrote on Instagram.

Khloe, who has never been one to mince her words, has been taking out her frustration either at the gym or online, writing a cryptic Instagram post last week."Never be fearful of letting go, for sometimes holding on can damage you deeper," she wrote. "Those scars run deep. There's a huge difference between giving up and letting go. Giving up means you are selling yourself short.

"It means allowing fear to limit your opportunities and keep you cemented in place. Stuck. Letting go means freeing yourself from something that is no longer beneficial to your personal growth. It means removing toxic people and toxic mindsets from your life so that you can make room for relationships and ideas that are conducive to your happiness and ever evolving personal expansion."

Meanwhile, she added that reconciling with estranged husband Lamar Odom, who is recovering from a traumatic brain injury, would be "the best dream."

"I mean, that would be like the best dream ... like, okay, I hope that first marriage could happen again,” she said.

“It's really hard to erase everything that happened. Just building a friendship back is what I'm doing now. It has nothing intimately, nothing at all, just pure love, and I want someone to learn how to love themselves again.
